Description

[Detailed description of the invention] Conventionally, combine harvesters have been equipped with a threshing device on one side of the machine base, a grain tank on the other side, and a transmission device between them. When inspecting, a removable opening/closing plate was attached to the wall plate on the outside of the grain tank and the wall plate on the side of the threshing device, and the opening/closing plate had to be attached and detached during maintenance inspection, which was extremely troublesome and not enough. Since it was not possible to obtain a suitable work space, maintenance and inspection work was difficult.

Further, in the case where the grain lifting device is installed at the end of the grain tank, if there is another device adjacent to the grain lifting device, it is extremely difficult to maintain and inspect the grain lifting device or to remove clogs.

The present invention provides a grain tank in a combine that allows maintenance and inspection of the transmission device installed between the threshing device and the grain tank and the grain lifting device installed at the end of the grain tank to be performed extremely easily and quickly. This machine is equipped with a threshing device on one side of a machine with a traveling device, an operation panel on the front of the other side, and a grain hoisting device on the front of the machine at the rear. In a combine that is provided with a grain tank and a transmission device is provided between the grain tank and the threshing device, the grain tank on the opposite side of the grain lifting device is pivoted on a machine base so as to be horizontally rotatable about a vertical axis. It is characterized by this.

The embodiments shown in the drawings will be explained below.
Reference numeral 1 denotes a threshing device mounted on one side of a machine base 3 having a traveling device 2. A pre-processing device consisting of a reaping device and a grain culm conveying device is attached to the front part of the threshing device so that it can be raised and lowered, and the rear part of the threshing device is mounted on one side of the machine base 3 having a traveling device 2. A cutter 4 is attached to the
A grain tank 6 having a grain thrower 5 at the front is provided on the other side of the machine, and an engine room 8a containing an engine 8 is provided below the cockpit 7 located at the front. There is.

Then, a pair of upper and lower bearings 9, 9 are fixed to the rear surface of the grain tank 6, and the vertical shaft 10 inserted through these bearings 9, 9 is connected to the cutter 4 and the machine base 3 with fittings 11, 11. A pin 12 supported and passed through the vertical shaft 10 faces the lower surface of the lower bearing metal 9 with a very small distance therebetween, and a leg 13 protruding from the lower front end of the grain tank 6 is connected to the machine base. Since it is placed on the weight sensor 13a provided in the grain tank 3, it senses the amount of grains in the grain tank 6, and the sensed amount is displayed on a display (not shown).

Further, between the threshing device 1 and the grain tank 6, there is a belt 17 stretched between a pulley 15 attached to the input shaft 14 of the grain tank 6 and a pulley 16 of the engine 8, and a belt 17 between the pulley 15 and the threshing device. Transmission devices such as belts are interposed to drive the No. 1 first transfer helical shaft, No. 2 transfer helical shaft, and blower shaft.
Drive 9.

In the above-mentioned combine harvester, the grain culms harvested and transported by the pre-processing device are threshed by the threshing device 1, and the sorted grains are put into the grain tank 6 by the grain lifting cylinder 22, When 6 is full, pull the aircraft to a transport vehicle on the road and press lever 2.
0 to close the shutter of the transfer spiral 21 at the bottom of the grain tank 6, and then
The grains are loaded into the transport vehicle by tilting.

When performing maintenance and inspection of the transmission device between the threshing device 1 and the grain tank 6 or the grain thrower 5, the locking member 23 of the grain tank 6 is released and the front part of the grain tank 6 is pulled out. Then, the grain tank 6 pivots outward about the vertical axis 12 as shown by the chain line in FIG. 4, the front part of the transmission is exposed, and the grain thrower 5 protrudes outward. maintenance and inspection can be carried out easily in a large space.

Moreover, when the grain tank is rotated, the belt 17 is loosened, so that the work can be carried out quickly without having to put your hand into a narrow space and remove the belt in advance.

As mentioned above, the present invention is a grain tank equipped with a threshing device on one side of a machine base having a traveling device, an operation panel on the front part of the other side, and a grain hoisting device on the front part of the rear side. and a transmission device is provided between the grain tank and the threshing device, in which the side of the grain tank opposite to the grain lifting device is pivotally supported on the machine base so as to be horizontally rotatable about a vertical axis, By pivoting the grain tank outward, the transmission between the threshing device and the grain tank is largely exposed, allowing easy maintenance and inspection in a large space.

In addition, since the grain tank rotates around the opposite side of the grain lifting device, the entire grain lifting device moves outward together with the grain tank, making maintenance and inspection of the grain lifting device and removing clogs easier. can be done.

Furthermore, when the grains in the grain tank are loaded onto the loading platform of a transport vehicle parked on the road, the grain lifting device of the grain tank is located immediately after the driving section, so the discharge port of the grain lifting device to the loading platform is positioning can be performed accurately and quickly.
